4(a+2)=14-2(3-2a)
mylen [45]

Answer:

All real numbers

Step-by-step explanation:

There is 3 possible solutions to a linear equation:

  • One solution -a unique x value that makes the equation true
  • No solution - a false statement is given after solving without a value for x
  • Infinite solution - a true statement is given after solving without a value for x

Solve using inverse operations:

4(a+2)=14-2(3-2a)

4a+8=14-6+4a

4a-4a+8=8+4a-4a

8=8

Is 8=8? Yes. Therefore this is a true statement with no value for x. Infinite solutions or all real numbers.

3x+7-6=(8/7)-0<br>Value of x?​
ArbitrLikvidat [17]

Answer:

\boxed{\sf x = \dfrac{1}{21}}

Explanation:

\rightarrow \sf 3x+7-6= \dfrac{8}{7}  - 0

simplify the following

\rightarrow \sf 3x+1= \dfrac{8}{7}

subtract 1 from both sides

\rightarrow \sf 3x+ 1 -1= \dfrac{8}{7}   - 1

simplify the following

\rightarrow \sf 3x= \dfrac{1}{7}

multiply both sides by 1/3

\rightarrow \sf 3x \cdot \dfrac{1}{3}= \dfrac{1}{7}\cdot \dfrac{1}{3}

simplify the following

\rightarrow \sf x = \dfrac{1}{21}

Factorise 9w² - 100<br><br><br>​
ohaa [14]

Answer:

9\, w^{2} - 100 = (3\, w - 10) \, (3\, w + 10).

Step-by-step explanation:

Fact:

\begin{aligned} & (a - b)\, (a + b)\\ =\; & a^{2} + a\, b - a\, b - b^{2} \\ =\; & a^{2} - b^{2} \end{aligned}.

In other words, (a^{2} - b^{2}), the difference of two squares in the form a^{2} and b^{2}, could be factorized into (a - b)\, (a + b).

In this question, the expression (9\, w^{2} - 100) is the difference between two terms: 9\, w^{2} and 100.

  • 9\, w^{2} is the square of 3\, w. That is: (3\, w)^{2} = 9\, w^{2}.
  • On the other hand, 10^{2} = 100.

Hence:

9\, w^{2} - 100 = (3\, w)^{2} - (10)^{2}.

Apply the fact that a^{2} - b^{2} = (a - b) \, (a + b) to factorize this expression. (In this case, a = 3\, w whereas b = 10.)

\begin{aligned}& 9\, w^{2} - 100 \\ =\; & (3\, w)^{2} - (10)^{2} \\ = \; & (3\, w - 10)\, (3\, w + 10)\end{aligned}.
